-{-	Note [Saving the current cost centre]

+{-        Note [Saving the current cost centre]
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 The current cost centre is like a global register.  Like other
 global registers, it's a caller-saves one.  But consider
-	case (f x) of (p,q) -> rhs
+        case (f x) of (p,q) -> rhs
 Since 'f' may set the cost centre, we must restore it
 before resuming rhs.  So we want code like this:
-	local_cc = CCC  -- save
-	r = f( x )
-	CCC = local_cc  -- restore
+        local_cc = CCC  -- save
+        r = f( x )
+        CCC = local_cc  -- restore
 That is, we explicitly "save" the current cost centre in
 a LocalReg, local_cc; and restore it after the call. The
 C-- infrastructure will arrange to save local_cc across the
 call.
 
 The same goes for join points;
-	let j x = join-stuff
-	in blah-blah
+        let j x = join-stuff
+        in blah-blah
 We want this kind of code:
-	local_cc = CCC  -- save
-	blah-blah
+        local_cc = CCC  -- save
+        blah-blah
      J:
         CCC = local_cc  -- restore
